“You wont shoot, he said.
That’s what you think.
You aint got but two shells. Maybe just one. And they’ll hear the shot.
Yes they will. But you wont.
How do you figure that?
Because the bullet travels faster than sound. It will be in your brain before you can hear it. To hear it you will need a frontal lobe and things with names like colliculus and temporal gyrus and you wont have them anymore. They’ll just be soup.”
– Cormac McCarthy, The Road (p. 64)
